The invention relates to a preparation method of high-dietary-
fiber oleogel. The preparation method comprises the steps of preparing
cellulose water dispersion, mixing the
cellulose water dispersion and hydrophilic
colloid, dispersing
oil phase in the mixed
system to prepare oil-in-water
emulsion, and treating the oil-in-water
emulsion to obtain the oleogel, or adding food additives to promote the
emulsion to form gel to obtain the oleogel, wherein the treatment method comprises a
drying method and a freezing method.
Cellulose particles service as emulsifiers, the hydrophilic
colloid serves as a stabilizer and a
thickening agent, the
cellulose particles are irreversibly adsorbed on the
oil water interface, the hydrophilic
colloid intersperse the cellulose
network structure to jointly form a three-dimensional
network structure, liquid fat can be constrained efficiently, the prepared emulsion gel has high stability, and long-time storage and transportation are facilitated; the method is simple, convenient, high in
dietary fiber content of the prepared high-dietary-
fiber oleogel, economic and
environmentally friendly; the oleogel is physical gel, does not change the
chemical property of the
oil phase, avoids generation of trans-
fatty acid, and has good application prospect in the fields of food, medicines and
cosmetics.
